I cannot access internet "only" after reboot

I'm having a problem with keeping an internet connection after every reboot. This is happening on two servers. Both have two 10/100/1000 NICs. One external, one internal. I can solve the problems by disabling and the re-enabling the connection but this is a pain being that I usually restart through remote desktop. In order to re-enable I must hook these servers up to monitors and mice....
All other network resources are available, "only internet" is lost!

I'm getting these errors in the event log but am having a hard time solving.
Event Type: Warning
Event Source: DnsApi
Event Category: None
Event ID: 11194
Date: 12/29/2006
Time: 10:14:34 AM
User: N/A
Computer: MYSERVER
Description:
The system failed to update and remove host (A) resource records (RRs) for network adapter
with settings:

Adapter Name : {#####################}
Host Name : MYSERVER
Primary Domain Suffix : mydomain.domain
DNS server list :
172.17.4.9, 172.17.4.7
Sent update to server : <?>
IP Address(es) :
172.17.4.24

The reason for this failure is because the DNS server sent the update either (a) does not support the DNS dynamic update protocol, or (b) the authoritative zone for the DNS domain name specified in these A RRs does not currently accept DNS dynamic updates.

Computer: MYSERVER
Description:
This computer was not able to set up a secure session with a domain controller in domain MYDOMAIN due to the following:
There are currently no logon servers available to service the logon request.
This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator.


Does anybody have an idea of how to solve this. This has only been happening since removing ISA but one of these was reformatted since.
My OS is Server 2003 std. DHCP is running on the .9 server above. All other workstations/servers are fine. Only these two, with two cards have problems.
 
OK, sounds like you have two NICs that are pointing to two different subnets.
Do both NICs have a default gateway configured? if so are you using RRAS to route traffic between the two subnets? My guess is not, so if you do a "route print" from the command line, which nic is your default route (0.0.0.0) pointing to? So if it is not pointing to your internal network and your Server is trying to resolve the IP for the DNS server, it may be looking for it on the wrong network. What I would do is remove the second NIC if not needed and use the route that other servers use to connect to the Internet. Need the Second NIC because it is the route to the Internet? - Configure RRAS service to route traffic, or Remove the default gateway of the external and using the route command, manually build a routing table that allows traffic bound for the Internet, to use the external NIC. This will fix the issue as you can have only one (0.0.0.0) default route on the server.

Phew....
Hope that makes sense.
 
Ohh by the way, you probably had ISA running in Firewall mode (I think that is what they call it) which would require two NICs. Since removing ISA you now have to use something like I mentioned above to route the traffic. RRAS should work best in this situation...

Cheers...
 
Thank you for writing WhoKilledKenny,
I took a look at the route print and it shows two default routes, the two NIC's pointing at two different gateways with 20 priority. I've never configured the RRAS before so could you please explain how to do that. The second NIC is for our clients to connect I guess. It was all set up before I got here with that ISA. If it makes any difference these are plugged into a DMZ.
Thanks in advance

 
What brand are your NICs? Broadcom? There are a lot of known issues with Broadcom NICs. They are the scourge of the server world. One typical solution is uninstalling any Broadcom software that was bundled, then removing and reinstalling the Broadcom drivers.

There's an intel pro and a 3com interlink, it's a Dell poweredge server. I noticed on one other server today that its priority was at 10 for the internal and 20 external. This one has internet after reboots. These two that aren't getting internet have 20 and 20. I don't want to mess anything up with like a persisitent route but I've never edited or changed those before. Have any ideas?

Something else I'd like to ask with these two servers. Now that I'm not using ISA I'm not sure how to assign them one of our public IP's for our client to access via internet. One is actually fine I think because its setup in PIX but the others a new addition. I don't know PIX. I looked at its config and saw the working server and address/port in the access-list but I'm not sure how to add a new IP (access-list outside_access_in permit)...and port into the pix. Then I'm not sure how to point it to this server, without ISA. Maybe I should post another thread for this?
